Linda Reisman has taken a significant leap into the realm of 3D printed housing in Canada. Faced with steep estimates from conventional builders for constructing a home on her land in Ontario’s Muskoka region, Reisman opted to invest nearly $700,000 in a robotic arm that can 3D print concrete walls layer by layer.
Expressing her enthusiasm for the speed and efficiency of 3D printing, Reisman highlighted the capability to print walls in a single day with minimal manpower. While she aims to utilize the arm for her own home construction, she also aspires to print homes for others to address the housing crisis in the country.
Reisman’s interest in 3D printing was piqued after the government emphasized the need for housing innovation, including 3D printing, and offered grants to promote its adoption. While some developers have integrated the technology into a few housing projects nationwide, its widespread acceptance remains uncertain.
Despite the potential of 3D printing, Reisman faces challenges in garnering support from traditional builders as her robotic arm solely prints walls, requiring additional tradespeople for tasks like installing doors, windows, roofing, and utility systems.
In Gananoque, Ontario, a townhome complex constructed using 3D printing technology stands as a successful example of this innovative approach. The project, backed by the Canada Mortgage and Housing Corporation (CMHC), involved a robot named Val and a small team in printing the concrete walls for the first floor, streamlining the construction process and reducing costs.
The Horizon Legacy company, behind this project, plans to offer affordable rental units through 3D printing, showcasing the potential for cost savings and expedited construction timelines in the housing sector. With ongoing advancements and collaborative efforts, the future of 3D printing in construction appears promising, albeit with the need for industry adaptation and regulatory considerations.
As the industry gradually embraces new technologies, including 3D printing, experts caution against overlooking the complexities of construction beyond the printing of walls. While 3D printing holds promise in addressing labor shortages and accelerating construction, it must be integrated thoughtfully alongside existing building regulations and practices.
Government initiatives and funding allocations underscore the growing interest in innovative housing technologies like 3D printing, signaling a shift towards modernizing the construction sector. Despite challenges and uncertainties, stakeholders like Horizon Legacy continue to push the boundaries of 3D printing in housing, envisioning a future where this technology revolutionizes home construction practices.
